Referring specifically to the drawing,van'd 30 more particularly to Figs. 1 to Ll, the brush head here illustrated is composed of a series of disks strung side by side on a spindle or rod 11 having at oneend-suitable cou pling means for connection to a,l handle. 3,5 The bristles 19. of the brush are clamped be tween the disks 10. `On one side of the disks are radial ribs 13 'starting ay short distance from the center openings 14 through which the spindle 11 passes, and extending 4o to the edge of the disks. In the opposite sides of the disksare radial grooves 15 of the same length and Width 'as theribs 13 and alternating therewith. `When thedisks are assembled on the spindle, the ribs of one 45 disk seat in the grooves of the neXt-7 this arrangement being followed' throughout the entire series of disks.

The bristles are tufts of steel Wire and they project from the edges ofthe disks 10. The inner ends of the bristles project ago the diameter of ,said openings being greater than the diameter of the spindle 11, so ,that a device may be mounted on sa-id spindle device is a. sleeve 1S which is taperedto- Ward one end and divided longitudinally into three sections 'as shown in Fig. 2.L .The sleeve Aisslidably mounted on the, spindle 11 and the inner ends of the :bristles abut against rthe outer surface of the sleeve.y As the sleeve is tapered, it \vill\be" seen that when it is moved in thedirection offits smaller end, the bristles, afterf ivear at the 'outer ends. of .the bristles is readily taken up, Theusleeve isoperated by afnut19 screwed on one end of the spindle, opposite' `the larger end ofy the sleeve, -With a Washer :20 interposed between said sleeve end and the. nut.

Before. the sleeve can be moved tozforce the bristles outwarchthe nut 21 must be backed, and after the adjustment is made, the nut is advanced, 'whereupon the sleeve is securely held on`r the spindle 11: The nuts' 19 and 20 are housed in the caps 16.

InY order to center the disks 10 on the spindle 11, said disks have radial' lugs 23v extending inward from l'the edge 'of the opening '14, saidlugs seatingv between .the sleeve sectionsand extending as far `as `the' spindle 11.
